Cast and crew members of the “Hawaii Five-0” reboot stood side by side on set at the Hawaii Film Studio at Diamond Head as they held together the ends of 10 maile lei to celebrate a milestone: the 10th season of the popular television show.

More than 100 people including state and film industry officials filled the set of the “Five-0” headquarters where Kahu Kordell Kekoa held a traditional Hawaiian blessing Thursday morning to kick off the season’s first day of filming.

Filming of the show’s elite task force battling crime in Hawaii began at the studio soon after the blessing ended.

Actor Alex O’Loughlin, who stars as Detective Steve McGarrett, attributed the show’s success to the entire cast and crew. “I really believe that it’s a testament to every single person on this show — every PA (production assistant), every grip, every electrician, everything.

“Actors get a lot of face time with the press ’cause we’re the faces on TV, but there’s so many hands in this, you know, making this happen and creating the end result from preproduction to actual production to postproduction,” O’Loughlin said during an interview with the Honolulu Star-Advertiser before filming started.

“I just wanna celebrate my crew and celebrate the ohana that we really do have here in front, and more so behind the camera, because that’s what’s done it,” he added.

Approximately 10.1 million viewers tuned in to the CBS show in its ninth season.

Hawaii film industry officials pointed out how rare it is for a television show to reach its 10th season.

Georja Skinner, chief officer of the Creative Industries Division of the state Department of Business, Economic Development and Tourism, said, “This kind of milestone doesn’t happen that often in television. Certainly, with all the new streaming aspects of the media industry now, to see a solid show on for 10 years is a wonderful milestone, and that’s a testament to the writers, to the actors, to everybody who are part of this.”

Film production of “Five-0” and the rebooted “Magnum P.I.” show, which is filming its second season in Hawaii, has garnered economic benefits for the state.

On average, a television series will have an $80 million dollar-plus impact, and that is just in production jobs, said Skinner, who attended the blessing. “But more so, it’s all the other trickle-down into the economy that’s so important.”

Peter Lenkov is executive producer and showrunner for both “Five-0” and “Magnum.”

“When you have a strong executive producer and showrunner like Peter Lenkov and his team, I think you see that with ‘Five-0’ and with ‘Magnum,’ the viewers want to see more of Hawaii,” Skinner added. “The fact that we have two series on the ground here helps us so much to be able to continue to provide those jobs and all the opportunities that the jobs bring.”

With the 10th season underway in filming “Five-0,” actor Dennis Chun, who plays Sgt. Duke Lukela, said, “I think that this 10th season, it’s going to be very remarkable, one full of emotion and action and lots of twists and turns. I’m very excited about this 10th season.”

“The fans should expect a great ride,” he said.
